How to get a perfect iguana hide as Arthur in RDR2

How to find a perfect Iguana hide as Arthur in Red Dead Redemption 2. I decided to make this video because I had a little bit of trouble with it and tried several times to get into Blackwater area as Arthur because I thought that was the only place to find Iguanas. The iguana hide is needed to craft some items such as the iguana big valley hat (as you can see me wearing in the video.) However, there is another area where you may find them and it is accessible for Arthur. It is an island directly across from the gang's Lemoyne camp in Chapter 3. Make sure to bring a varmint rifle at it is probably the best weapon for killing the Iguana while making sure the hide is in top condition, but make sure to aim for the head as a bodyshot might not kill it as you can gather from my fuckup in the video.
